THLC134100WL - 100Amp Circuit Breaker Description

THLC134100WL - 100 Amp Circuit Breaker

The THLC134100WL is a 100-amp, 3-pole current-limiting circuit breaker designed for use in your commercial and industrial electrical distribution systems where high interrupting capacity is required. Built with a non-interchangeable trip unit, this unfused breaker helps you to provide dependable circuit protection against overcurrent conditions while maintaining compatibility with equipment designed for the THLC1 platform. Its compact footprint, combined with included line-side and load-side lugs, simplifies installation and replacement in existing systems. Engineered for long service life, the THLC134100WL is built to last and is well-suited for facilities that require reliable protection of feeders, branch circuits, and distribution equipment. With interrupting ratings of 150kA at 480VAC and 200kA at 240VAC, this current-limiting circuit breaker is designed to help you minimize the effects of high fault currents and protect connected electrical infrastructure. Whether used in manufacturing facilities, commercial buildings, institutional environments, or other demanding applications, the THLC134100WL delivers the form, fit, and function needed for compatible electrical systems.
